2 Presentation Outline Introduction to MIA Program Overview and History Module 1: Review of Form A Instructions Definitions Guidance/Best Practices Significant Updates Naming Conventions for Annular Spaces Module 2: Form A Form A Overview Form A Use with Examples Form A 2-Year Example and Data Transfers Form B Overview Form B Use with Examples Form B Data Transfers

3 FORM B Overview Form B can accommodate up to 6,000 well entries Only compatible with Microsoft Excel versions 2007 or later It contains limited instructions in the form of embedded comments Form B is intended for operators/owners who know what inspection components apply to the different wells in their inventory If they are uncertain, they are advised to download Form A and the instructions and profile their inventory to determine what inspection components are required on a well type-by-well type basis Once they have the inspection components defined for their well inventory, they should be capable of using Form B without much trouble

4 Form B Overview

5 Form B Use with Examples Form A is designed to help operators understand how to set up and populate Form B This is accomplished by entering data into the first 9 fields (numbered 1 9) in Form A it may also be necessary to enter one date Use the specified fields on Form A to determine what fields on Form B must be populated with data

6 Form B Use with Examples In this example, Operator A has reviewed their inventory and determined they have the following well design: 354 four-string gas wells in coal areas producing through a tubing assembly similar to the CATALANO 2H design

7 CATALANO 2H

8 Form B Use with Examples In this example, Operator A has reviewed their inventory and determined they have the following well design: 210 three-string gas wells with annular production with the primary production through a tubing assembly and annular gas production inside of the intermediate casing similar to the SWANK 4H design

9 SWANK 4H

10 Form B Use with Examples In this example, Operator A has reviewed their inventory and determined they have the following well design: 280 two-string combo wells producing oil through a rod and tubing assembly and annular gas inside of the surface casing and outside of the production string similar to the WELSH NO. 3 design

11 WELSH NO. 3

12 Form B Use with Examples In this example, Operator A has reviewed their inventory and determined they have the following well design: 617 combo wells equipped only with freshwater casing only and producing oil through a rod and tubing assembly and gas outside of the tubing and inside the surface casing similar to the COSTELLO NO. 1 design

13 COSTELLO NO. 1

14 Important Notes Enter the well design criteria in Form A to profile inventory and determine what parameters need to be measured quarterly for each well design The well type and production information will dictate how to fill out the columns in Sections 13 and 14 of Form B. The number of casing strings in the well design will determine what columns must be completed in Sections 15, 16 and 17 of Form B, JUST LIKE IN FORM A The status of the production annulus (Section 14), must be filled out appropriately on Form B based on actual conditions, unless that annulus is produced If the well is routinely vented, or there are any leaks, Section 18 must be completed on Form B

15 Main Closing Points: Profile your wells in order to divide them into distinct groups Complete one row in Form A for each distinct group, remembering to enter at least one date for each entry Gray or block out unnecessary cells in Form B based on Form A designs evaluated Use your own software/tools to complete well integrity assessments and copy and paste required well data into Form B prior to submitting annual report to DEP

16 Form B Data Transfers After all annual inspection data are entered in Form B and validated by the operator/owner, select the button labeled Create Data Summary Sheet for Annual Report to submit to the Department
